Hayden places these four blocks into a bag.

A picture shows 4 blocks labeled A, B, C, and a star.

Question

He picks one block without looking.

What is the probability that the block Hayden picks has a letter on it?

Answer options with 4 options

A. One-Fourth

B. One-Thirds

C. Tow-Thirds

D. Three-Fourths

Option D

Step-by-step explanation:

There are four total blocks.

Number of total events: 4

Three blocks contain letters.

Number of preferred events: 3

There is a 75% (or 3/4) chance that Hayden will pick a letter block.

Therefore, option D should be the correct answer.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
